For a rivet joint under eccentric loading, there exist a primary shear stress and an additional shear stress due to the eccentric load giving a moment about the centroid of the rivet joint.(adsbygoogle = window.adsbygoogle || []).push({});

The formula to calculate the force giving the additional shear stress is...

F_{i}=P x e x r_{i}/ (Summation of r_{i})

where P is the eccentric load, e is the distance from the load to the centroid and r is the distance a particular rivet is from the centroid.

My question is, how did this formula come about? What are the assumptions made for this to come true.
